Application filed March 11, 1910. Serial No. 548,529.

To all whom it may concern:

Be it known that we, EDWARD D. CHANI- NEL and JOHN R. HENRY, citizens ofthe United States, residing at Seward, in the county of Westmoreland andState of Pennsylvania, have invented new and useful Improvements inProcesses for Applying Calks to Horseshoes, of which the following is aspecification.

The invention relates to an improved process for completing horse shoesin the application of a toe calk, being more particularly directed to aprocess by which the toe calk is secured in proper alinement and by aperfect weld to the shoe through a single heating.

In the usual manner of applying toe calks to a horse shoe by welding,considerable difficulty is experienced in applying the calk to the shoein proper position and alinement and in securing such intimate contactbetween the surfaces of the calk and shoe as to permit a proper welding.In the ordinary process of completing the shoe by applying the calk, theshoe and calk are heated as separate pieces and the welding processcarried out when the pieces are removed from the fire. As the calkincludes a great deal less material than the shoe it will cool morerapidly than the shoe when removed from the fire with thedisadvantageous result of having the two parts at relatively differentdegrees of heat with the effect to prevent a perfect weld. Furthermore,the separate heating of the shoe and calk expose the con tactingsurfaces of the respective parts to the formation or accumulation ofscale, from any of the well known causes, which scale will defeat aproper welding of the parts. If the scale is mechanically removed, theloss of time incident thereto will ordinarily permit such a cooling ofthe parts as to interfere with their proper welding.

The main object of the present process is to eliminate all of the abovenoted objections by initially securing the calk and shoe mechanicallytogether while the parts are cold, the securing means being utilized forproperly alining or positioning the calk on the shoe. By such mechanicalsecuring the engaging surfaces of the calk and shoe are brought intosuch intimate contact as to prevent the formation or accumulation ofscale therebetween and, at the same time, permit the calk and shoe in asingle heating to be brought to a proper temperature which,

while in the fire, causes a sufficient adhesion between the calk and theshoe as to initially secure these parts so that the usual weldingoperation will form a perfect integral joint. Furthermore, themechanical connecting means between the calk and shoe, in addition tothe functions noted, have another and important advantage in that theyprovide projections integral with the calk which, in the weldingoperation, become in effect an integral part of the body of the shoe,thereby, in a measure, relieving the weld joint between the calk andshoe of the greater portion of the strain incident to the use of theshoe.

In carrying out the present process, reference will be had particularlyto the accompanying drawings, as illustrative of one embodiment of themechanical details of such process, in which drawings 2- Figure 1 is atop plan of a horse shoe with the parts constructed for the carrying outof the process. Fig. 2 is a sectional view on the line 22 of Fig. 1.Fig. 3 is a sectional view on the line 8- 3 of Fig. 1 with the toe calkset back. Fig. 4: is a similar view with the calk set forward.

In carrying out the process, the horseshoe 1, during its initialconstruction, is formed in the toe portion with a centrally disposedaperture 2, preferably of angular formation and with oppositely disposedrecesses 3 alined with the aperture and with each other transverse theshoe. The aperture 2 extends entirely through the body of the shoe whilethe recesses 3 preferably, though not necessarily, extend but partlythrough such body. The walls of the aperture 2 incline with relation toeach other inwardly and upwardly so that the bottom or entrance to theaperture 2 is larger than the top.

The calk 4 comprises a body or calk section which may be of any of theusual or preferred shapes in plan, longitudinal, or transverse section,that is constructed in any desired manner to provide an engaging surfaceadapted for any particular use. The calk section is provided inalinement with one edge with a wedge shaped projection 5 having 'alength exceeding the thickness of the shoe at the aperture 2. Beyond theprojection 5, the calk is provided with dowels 6, designed when theprojection is seated within the aperture 2 to engage in the recesses 3and thereby properly center and aline the calk on the shoe. Theprojection 5 is, adjacent the calk section, of such size with relationto the lower end of the aperture 2 that when said projection is driveninto and through the aperture a frictional engagement will be hadbetween the projection and the walls of the aperture with the effect tohold the calk in proper position after initial application to preventaccidental separation of the parts in the reversal of the shoe tocomplete the mechanical connection. The upper portion of the projection5 is preferably, though not necessarily, of slightly less sectionaldimensions than the correspondingly alined sectional dimensions of theaperture, whereby to insure a proper fitting of the parts in the eventthe projection should become slightly distorted or bent prior to itsapplication.

In carrying out the essential steps of the process, the partsconstructed as described are first mechanic-ally connected in thefollowing manner. The calk is applied to- Y the shoe so that theprojection 5 is seated in an intimate contact between the surfaces oforation whatever.

the calk and shoe. The article in this form is then placed in the fireand brought to a proper welding heat, and, after removal, welded in theusual manner.

By the improved process the intimate contact between the calk and. shoeprevents the formation or accumulation of scale on the contactingsurfaces, whereby one of the serious objections to the usual welding ofthese parts is removed. Furthermore, bot-h parts are heated with theircontacted surfaces in engagement, securing by the heating an initialadhesion. The use of the projection and dowels will center and aline thecalk in exactly proper position, relieving the blacksmith of thenecessity of giving this part of the process any attention or consid-The projection 5 and dowells 6 will, by the welding, become such anintimate part of the shoe body as to materially strengthen theconnection and in a very considerable degree relieve the Welding jointbetween the flat surfaces of the calk and shoe of the breaking strain atthis point.

As shown in Fig. 3, if the calk is applied with the projection 5extending from the forward edge thereof the main body or calk sectionwill be set back with relation to the forward edge of the shoe, whilewith the parts reversed the calk will be set forward, as shown in Fig.4.

It is of course to be understood that the term horse shoe herein ismeant any shoe designed to be applied to an animal for protectivepurposes, and that while the illustrated construction of the projectionand dowels is that preferred, it will of course be apparent that wecontemplate the use of any number of such parts and anyrelativearrangements thereof that will permit of the functions described.

While the invention and process is illustrated and described forapplying toe calks, it is obvious that it is equally applicable to thesecuring of heel or special calks, and that the invention can, withequal facility, be applied to the ordinary or any special type of horseshoe.

Having thus described the invention, what we claim as new is The hereindescribed process in initially securing a horse shoe and calk togetherfor welding, consisting in forming the calk with a projection extendingbeyond the welding surface of the calk, and of a length to pro jectthrough and beyond the surface of the shoe, and heading the projectingportion thereof to bind the welding surfaces of the shoe and calk inintimate contact prior to the welding operation.

In testimony whereof we afiix our signatures in presence of twowitnesses.
